SCOPING INFORMATION Packet Prepared by: Landrum & Brown, Inc. for: Port of Seattle Seattle, Washington July 2018. I. INTRODUCTION. The Port of Seattle prepared a Sustainable Airport Master Plan (SAMP) to establish a blueprint for changes at Seattle-Tacoma International Airport (Sea-Tac or Airport) to meet future demand. The SAMP was completed in 2018 and identified a Long-Term Vision, as well as a set of Near-Term Projects that are planned for construction by 2027.

2 The Port of Seattle (Port) and the Federal Aviation Administration (FAA) are initiating an environmental review to evaluate and disclose the potential environmental effects of the Near-Term Projects (Proposed Action). It is important to note that neither the Port of Seattle nor the FAA have issued approvals on the Near-Term Projects (Proposed Action). No approvals or implementation of the proposed action will take place before the completion of the environmental review process that will follow the requirements of the National environmental Policy Act and the State environmental Policy Act. National environmental Policy Act (NEPA).

3 Prior to implementation the FAA must comply with the National environmental Policy Act of 1969 (NEPA) when implementing a Proposed Action involving one or more federal actions. In this case, the Port of Seattle is seeking the FAA's unconditional approval of the Near-Term Projects depicted on the Airport Layout Plan for the Airport and may request federal funding to implement the Proposed Action. Because these are federal actions that the FAA would undertake, the environmental analysis and documentation must comply with the requirements of NEPA as implemented in the regulations adopted by the Council for environmental Quality (CEQ), 40 1500 et seq.

4 , as well as FAA Order , environmental Impacts: Policies and Procedures, and FAA Order , National environmental Policy Act (NEPA) Implementing Instructions for Airport Actions. Based on coordination and direction from the FAA, a NEPA environmental Assessment ( NEPA EA ) will be prepared to determine if significant impacts are likely to occur with the implementation of the Proposed Action. If the analysis indicates significant impacts that cannot be mitigated as a result of implementing the Proposed Action, a NEPA. environmental Impact Statement (EIS) would be required. State environmental Policy Act (SEPA). Under Washington's State environmental Policy Act (SEPA), environmental review is required for any proposal which involves a government "action," as defined in the SEPA.

5 Rules (Washington Administrative Code (WAC) 197-11-704), and which is not categorically exempt (Chapter 197-11 WAC PART NINE - CATEGORICAL EXEMPTIONS). Project actions involve an agency decision on a specific project, such as approval of a construction project. As the Port of Seattle is proposing the construction of the Proposed Action, this environmental review will be prepared in accordance with SEPA. requirements, WAC 197-11, as well as the Port of Seattle Resolution 3650. Sustainable Airport Master Plan Page 1. environmental Review Process SCOPING INFORMATION Packet The Port of Seattle, as SEPA lead agency, acknowledges that there is public interest and concern about the potential environmental impacts of implementing the Proposed Action.

6 Based on that level of concern and the potential for impacts that may occur with the implementation of the Proposed Action, the Port of Seattle has determined that a SEPA environmental Impact Statement (EIS), known as a SEPA EIS, will be prepared. The Port and FAA intend to prepare the NEPA EA/SEPA EIS in a coordinated manner to make review easier by the public, agencies, and potentially affected Tribes. The SAMP includes a Long-Term Vision for Sea-Tac which includes projects that are not ripe for environmental review at this time, as they require further study and are not reasonably foreseeable. Before any of the Long-Term Vision projects are implemented, the appropriate environmental review process will be conducted.

7 The Near-Term Projects (the Proposed Action) are the subject of a phased environmental review process to comply with SEPA. SEPA requires phased review for proposals that are ripe for environmental review and excludes from consideration actions that are not yet ripe for review. The Near-Term projects will be the subject of the first phase of the environmental review process because they are ripe for review. The Long-Term Vision projects will be subject to a later phase of environmental review when they become ripe for review. Phased review is not required under NEPA. The Port and FAA anticipate conducting additional environmental review in the future regarding the longer-term projects identified in the SAMP; however, those potential future actions are not ripe for decision or environmental review at this time.

8 During the environmental review process, a multi-disciplinary team of experts will study the potential environmental impacts of the Near-Term Projects, determine whether the environmental impacts are significant, and, if so, evaluate ways to mitigate those impacts. Before these studies begin, a 60-day period is reserved for the public to provide input on the range of issues and alternatives that should be studied as part of the environmental review. This 60-day period is known as SCOPING and represents the formal kick-off of the environmental review process. This Agency and Public SCOPING INFORMATION Packet provides INFORMATION about SCOPING and the environmental Review Process.

9 The Port has developed user-friendly tools, including public open houses and an online open house, to make it easier for everyone to provide input to the scope of the environmental review. More INFORMATION is available about the SAMP at: The following INFORMATION is presented in this packet for review during SCOPING : Overview of SCOPING (Section II).

10 OVERVIEW OF SCOPING . SCOPING is an early and open process for determining the scope of issues that will be addressed in the environmental review document, soliciting input regarding the Proposed Action and reasonable alternatives, and for identifying concerns regarding the potential environmental effects of the Proposed Action. Comments received during SCOPING will be reviewed and taken into consideration during the preparation of the NEPA and SEPA. analyses. How Will the SAMP Near-Term Project Alternatives be Identified? In addition to the Proposed Action, the NEPA EA/SEPA EIS will evaluate a range of alternatives to the Proposed Action to ensure other feasible and reasonable solutions have been considered.
